Overview

The LA4708N is a BTL two-channel power IC for car audio developed in pursuit of excellent sound quality. Low-region frequency characteristics have been improved through the use of a new NF capacitor-less circuit, and crosstalk which causes “muddy” sound has been reduced by improving both circuit and pattern layout. As a result, the LA4708N provides powerful bass and clear treble. In addition, the LA4708N features on-chip protectors and standby switch.

Features

•High power : supports total output of 30W +30W (VCC= 13.2V, THD = 30, RL= 4Ω)

•Supports RL= 2Ω(PO= 30W when VCC= 13.2V, THD = 10)

•Designed for excellent sound quality (fL <10Hz, fH= 130kHz)

•NF capacitor-less

•Any on time settable by external capacitor

•Less pop noise

•Standby switch circuit on chip (microprocessor supported)

•Various protectors on chip (output-to-ground short/output-to-VCCshort/load short/overvoltage/thermal shutdown circuit)
